The economy is terrible and incumbent governors naturally get some blame. New York Governor David Paterson has a 28% approval rating(Siena Poll -PDF). Pennsylvania Governor Ed Rendell is at 47% approval (Quinnipiac poll). In the latest New Jersey poll by Fairleigh Dickinson University, Governor Jon Corzine lands in the middle, with 40% approval and 46% disapproval. Worse yet, we find him well below 50% in the re-elect numbers, trailing Chris Christie 32%-41%. This poll has 751 registered voters for a margin of error of 4%. I don't think there is anything to say that I haven't said before.
The average of all five 2009 polls from four different pollsters leaves Corzine trailing Christie 37.6%-39.2%. Never mind about 50%, we do not have any polls with Corzine above 40%. The average of the six polls with approval-disapproval gives us 41.3% approve, 46.3% disapprove.
